OK, I'll tell everyone what I've understood. Unlike QNH and QFE which are
altimeter settings, QNE is an
altimeter reading - it is an indication on your altimeter at landing when you set it to 1013.2/29.92. Of course it is as changeable as QNH and QFE, so you need to get it each time from someone. And then, when landing:
- instead of setting QNH on alt and reading THR elev when you land, and
- instead of setting QFE on alt and reading 0 when you land,
- you set standard setting 1013.2 and read QNE when you land.
Did I get it right?
To answer a question from
Crash one I'll now put my Math MSc hat on:
- I just derived on the back of an envelope that QNE = (1013.2 - QFE) x 30, but:
- QFE = QNH - (elevation/30), so:
- QNE = (1013.2 - QNH) x 30 + elevation
Quod Erat Demonstrandum
You just missed brackets
